Yunnan Power Grid Tuam Txhab ntawm Tuam Tshoj Southern Power Grid Co., Ltd. tshaj tawm rau lub Cuaj Hli 27 tias qhov sib npaug sib kis ntawm Yunnan "West-to-East Fais Fab Kis" tau tshaj 1.7 trillion kilowatt-teev, ua lub luag haujlwm zoo hauv kev txhim kho. East-West Coordination Department thiab ecological ib puag ncig tiv thaiv. Tau txais daim ntawv thov cov cuab yeej tseem ceeb hauv daim phiaj hluav taws xob, xws li switchgear, cais cov keyboards, xob laim ntes, lub tshuab nqus tsev vacuum breakers, tso tawm fuses thiab transformers, thiab lwm yam.
Raws li cov lus ceeb toom, thaum Lub Yim Hli 1993, 220 kV kab txoj haujlwm los ntawm Lubuge mus rau Tianshengqiao tau nruab nrog cov khoom siv qib siab hloov thiab cais cov hloov pauv thiab tau ua tiav tiav. Yunnan pib xa hluav taws xob raws caij nyoog mus rau Guangdong, ua raws cov kauj ruam ntawm "kev xa hluav taws xob los ntawm sab hnub poob mus rau sab hnub tuaj". thawj kauj ruam. Xyoo 2024, nrog rau kev ua tiav ntawm ntau qhov chaw ua haujlwm xws li 500 kV Delan Line, 500 kV Longyang substation (nrog rau kev ua haujlwm siab transformers thiab lub tshuab nqus tsev Circuit Court breakers), thiab 500 kV Guanghui substation (nruab nrog poob- tawm fuses thiab xob laim ntes) Ua tiav thiab muab tso rau hauv kev ua haujlwm, Yunnan tau tsim ib 500-kilovolt daim phiaj tseem ceeb nrog "plaub kab rov tav, plaub ntsug thiab ib qhov chaw", uas qhia cov yam ntxwv ntawm "lub xeev AC thiab DC kev ua haujlwm sib luag, hauv tsev { {9}}Circuit DC qhov ntev-ntev loj-muaj peev xwm kis tau tus mob, thiab txawv teb chaws fais fab kis tau tus mob thiab txais tos nyob rau hauv ntau cov lus qhia". Ntawm lawv, lub peev xwm xa hluav taws xob ntawm "West-to-East Fais Fab Kis" tau nce los ntawm thawj 300, 000 kilowatts mus rau 42.2 lab kilowatts.
Tshaj li 31 xyoo dhau los, Yunnan Power Grid Tuam Txhab tau nrawm rau kev siv cov khoom siv hluav taws xob loj hla lub xeev thiab hla cheeb tsam xa hluav taws xob thiab kev hloov pauv cov phiaj xwm. Nws tau ua tiav ua tiav Wudongde lub chaw nres tsheb fais fab kis tau tus mob nrog cov kev sib tw tshaj plaws thiab qhov ntev tshaj plaws tau tsim cov kab hauv xeev. Txoj haujlwm no tau txais kev ua haujlwm zoo ntawm lub tshuab nqus tsev vacuum thiab cais cov hloov pauv; thawj qhov project Yongfu DC nrog "peb-chaw nres tsheb sib koom ua ke" ntawm chaw nres tsheb hloov pauv, substation thiab cov chaw nres tsheb them nyiaj. Nws txoj haujlwm ua haujlwm tau zoo yog nyob ntawm kev tswj xyuas qhov tseeb thiab kev tiv thaiv tus ntes; thawj ± 500,000 Yunnan-Guizhou Interconnection DC Project, uas "hloov ob lub davhlau ya nyob twg nrog peb lub davhlau ya nyob twg", tau ua tiav kev sib kis tau zoo thiab kev faib hluav taws xob hluav taws xob los ntawm kev hloov pauv qib siab thiab kev siv tshuab hluav taws xob... Ntau qhov haujlwm tau teeb tsa ntau thawj nyob rau hauv lub ntiaj teb no thiab lub teb chaws, thiab paub lub domestic kev hloov ntawm cov khoom tseem ceeb thiab cov khoom, xws li hloov cov txee, cais keyboards, xob laim ntes, lub tshuab nqus tsev breakers, tso tawm fuses, thiab lwm yam.
Thaum lub sij hawm "14th Tsib-xyoo Plan", Yunnan xeev yuav ntxiv ntau tshaj 50 lab kilowatts ntawm lub zog tshiab ntsia muaj peev xwm. Lub Tuam Txhab Yunnan Power Grid yuav ua kom nrawm rau kev tsim kho ntawm kev txhawb nqa cov phiaj xwm sib txuas thiab txuas ntxiv txhim kho cov txheej txheem kev sib npaug ntawm cov peev txheej thiab cov peev txheej loj ntawm kev faib cov peev txheej. Txhim kho qhov kev teeb tsa ntawm transformers, ntxiv dag zog rau kev ntseeg siab ntawm switchgear thiab fuses, thiab xyuas kom meej tias lub zog huv si tau nce mus txog ntau dua 98%, ntxiv txhawb kev loj hlob ntsuab thiab ruaj khov ntawm Yunnan "West-to-East Power Transmission".
